Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of cable braiding equipment, and in particular, to a special cable braiding equipment that is resistant to high temperatures. Background Art

[0002] In fields such as power transmission and industrial control, high-temperature resistant cables must operate stably in high-temperature environments. Their outer walls are typically braided with a high-temperature resistant layer to enhance insulation and structural strength. Although traditional cable braiding equipment is capable of multiple spindles working together, it faces the following technical challenges in actual production:

[0003] Inefficient threading: Existing braiding equipment typically features dozens or even hundreds of spindles, each requiring its own spool installation and wire guidance. Due to the large number of spools distributed on a circular track, operators must frequently maneuver around the machine to thread the yarn, resulting in a long and labor-intensive process.

[0004] Large spatial limitations: The multi-spindle layout results in a compact machine structure, with close spacing between adjacent spools. This limits operator hand space and makes efficient wire pulling difficult. This is especially true when working with high-strength fiber wire used in high-temperature specialty cables, which presents further challenges due to its high hardness and toughness.

[0005] In response to the above problems, there is an urgent need for a cable braiding machine that can significantly improve the online efficiency of multi-spool braiding equipment and reduce the intensity of manual operation. Summary of the Invention

DETAILED DESCRIPTION

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0039] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0040] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0041] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0042] In the description of this embodiment, the terms "up", "down", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] like Figures 1 to 8 As shown, it shows a high-temperature resistant special cable braiding device in one embodiment of the present invention, which is used to braid a high-temperature resistant layer on the outer peripheral wall of a cable 1. It includes a workbench 2, and a ring track 3 is provided on the top surface of the workbench 2. The ring track 3 is an annular metal guide rail installed on the braiding machine frame. A through hole for the cable 1 to pass through is opened in the middle of the workbench 2. The ring track 3 is arranged in a concentric ring shape with the axis of the through hole; a number of spindles 4 are arranged at intervals along the ring track 3 and are all slidably set on the ring track 3. The rollers or sliders at the bottom of the spindles 4 roll or slide along the ring track 3, thereby driving the spindles 4 to move along a fixed trajectory. Each spindle 4 is detachably provided with a bobbin 5, which is used to wind the wire for braiding the high-temperature resistant layer.

[0045] It should be noted that the primary function of the circular track 3 is to constrain the motion path of the spindles 4, ensuring that their orbital trajectory conforms to the braiding process requirements (e.g., a figure-eight or circular pattern), thereby allowing the wires to intersect and form a mesh-like structure. Specifically, as the spindles 4 move along the circular track 3, the spools 5 can rotate or revolve with the spindles 4, while the wires are pulled and rotated to pay out. The motion trajectory of the spindles 4 along the track (e.g., a figure-eight pattern) determines the angle and density of the wire crossings, ultimately forming the texture of the braided layer. For example, in a 48-spindle braiding machine, the circular track 3 divides the spindles 4 into two groups (e.g., an inner ring and an outer ring). The two groups of spindles 4 move in opposite directions along the circular track 3 in a figure-eight pattern. After the wires are released from the spools 5, they alternately cross at the braiding points, forming a tightly woven mesh.

[0046] In addition, a cylinder 6 is provided in the middle of the workbench 2. The cylinder 6 is located inside the annular track 3 and is coaxially arranged with the through hole. A plurality of wire guides 7 are arranged at intervals on the outer peripheral wall of the cylinder 6. Each wire guide 7 includes a push rod 72 and a wire swing rod 71. The push rod 72 is fixedly provided on the outer peripheral wall of the cylinder 6. The push rod 72 is a hydraulic rod or an electric push rod. The movable end of the push rod 72 can be telescopically moved along the axial direction of the cylinder 6. One end of the wire swing rod 71 is hinged to the movable end of the push rod 72, and the other end is provided with a connecting block 73. The connecting block 73 is used to connect the wire end of the wire on the spool 5. The wire swing rod 71 can swing vertically around the hinge axis to move the wire end from the position of the spool 5 to the braiding position of the outer peripheral wall of the cable 1 through the connecting block 73.

[0047] For example, Figure 1 As shown, it should be noted that, first of all, in order to facilitate the orderly pulling of wires through the wire swing rod 71, rectangular areas are divided on the workbench 2. The number of rectangular areas is the same as the number of wire swing rods 71 ​​and the two correspond one to one. Each wire swing rod 71 only needs to pull the cable on the spool 5 within the corresponding rectangular area. This not only avoids workers from making mistakes when pulling the wires, but also ensures that the cables on each spool 5 are pulled in an orderly manner by the wire swing rod 71, preventing the occurrence of knots and entanglements between multiple cables.

[0048] Specifically, when the wire needs to be put on, the conductor swing arm 71 first swings a certain angle to make the connecting block 73 be closest to the spool 5. The operator then installs the wire end on the connecting block 73 and repeats this wire pulling operation until all the wires on the spools 5 are connected to the conductor swing arm 71. The conductor swing arm 71 then swings vertically synchronously until the connecting block 73 on the conductor swing arm 71 presses against the outer wall of the cable 1. The worker then only needs to stand in place to easily and preliminarily fix the wire ends of all the wires to the outer wall of the cable 1, preparing for the subsequent winding and braiding work. During the weaving process, because each push rod 72 corresponds to a wire rocker 71, when the cable 1 is pulled by the traction wheel and moves up along the cylinder 6, the two relatively arranged wire rockers 71 can be located at the same height of the outer wall of the cable 1, and the heights of the other relatively arranged wire rockers 71 are successively reduced to ensure that the cable 1 can be limited in the height direction to prevent the cable 1 from shaking during the weaving work. At the same time, the spindle 4 slides along the annular track 3, driving the bobbin 5 to move, and the wire is guided to the periphery of the cable 1 through the wire rocker 71 for weaving.

[0049] In summary, by providing a retractable push rod 72 and a swingable wire swing arm 71, the operator does not need to move around the machine frequently, and only needs to complete the installation of the bobbin 5 and the connection of the wire end in a fixed area, which greatly reduces the online operation time and reduces the labor intensity. At the same time, the wire member 7 is located on the inner side of the annular track 3, providing the operator with a more spacious hand movement space, solving the problem of large space limitations of traditional equipment, especially when processing high-strength fiber wires, the difficulty of online operation is significantly reduced. Specifically, when the bobbin 5 is replaced, the push rod 72 can quickly adjust the wire swing arm 71 to the initial position of the bobbin 5, automatically grab the wire end through the connecting block 73, and guide the wire end to the weaving position through vertical swinging. According to actual measurements, the use of this technical solution can greatly shorten the online time, significantly improve production efficiency, and reduce labor costs.

[0050] In some examples, a mounting plate 10 is fixedly mounted on the movable end of the push rod 72. Mounting plate 10 is a long, flat plate structure that is parallel to the top surface of the movable end of the push rod 72. The wire swing arm 71 is hinged to the mounting plate 10 via a hinge axis, which is fixedly connected to the wire swing arm. A driver 11 is mounted on the mounting plate 10. Driver 11 can be an electric push rod or a rotary motor. If it is a rotary motor, its power output engages with a gear on the hinge axis of the wire swing arm 71 through a gear transmission, enabling driver 11 to drive the wire swing arm 71 to swing vertically around the hinge axis.

[0051] For example, Figure 4 and Figure 5As shown, when the conductor pendulum 71 needs to be swung, the driver 11 is started, and the conductor pendulum 71 is driven to rotate around the hinge axis through the transmission mechanism. For example, the rotary motor drives the conductor pendulum 71 to swing through gear engagement, thereby moving the connecting block 73 from the position of the spool 5 to the weaving position. The extension and retraction of the push rod 72 and the driving action of the driver 11 can be coordinated and controlled by the control system to achieve automated operation. The setting of the driver 11 realizes the automation of the swing of the conductor pendulum 71, eliminating the need for manual swinging, further reducing the labor intensity of the operator, and improving the efficiency and accuracy of the online operation. At the same time, automated control can ensure that the swing angle and position of the conductor pendulum 71 are accurate, thereby ensuring the stability of wire guiding.

[0052] In some examples, an arcuate groove 730 is defined at one end of the connecting block 73 away from the wire swing arm 71, with the axis of the arcuate groove 730 being perpendicular to the swing direction of the wire swing arm 71. A compression bar 74 is provided on the connecting block 73. The compression bar 74 is a rectangular block that is slidably disposed within the arcuate groove 730, with its sliding direction being perpendicular to the axis of the arcuate groove 730. The compression bar 74 and the connecting block 73 can be slidably connected via a spring or a screw-nut mechanism. For example, a screw can be provided on the connecting block 73, with the compression bar 74 being threadedly connected to the screw, and the compression bar 74 can be slidable by rotating the screw.

[0053] For example, Figure 3 and Figure 4 As shown, when a thread needs to be connected, it is placed in the arcuate groove 730 and the clamping bar 74 is pushed and slid toward the arcuate groove 730, so that the clamping bar 74 and the arcuate groove 730 cooperate to clamp the thread. As the wire swing arm 71 swings, the clamping bar 74 maintains the clamped state on the thread, ensuring that the thread does not fall off. When the thread needs to be replaced, the clamping bar 74 is slid in the opposite direction to release the thread.

[0054] The arrangement of the arc-shaped groove 730 and the clamping strip 74 securely clamps the thread end, preventing it from falling off during the movement of the conductor swing arm 71, thereby improving the reliability of the threading operation. Furthermore, the clamping structure is simple and easy to operate, allowing the operator to connect and disconnect the thread end with a simple operation, saving time.

[0055] In some examples, the compression strip 74 is arc-shaped and coaxially arranged with the arc-shaped groove 730. Its side facing away from the arc-shaped groove 730 is a curved pressure surface 741, the curvature of which matches the curvature of the outer wall of the cable 1. When the conductor swing arm 71 swings onto the outer wall of the cable 1, the curved pressure surface 741 contacts the outer wall of the cable 1. Multiple conductor swing arms 71 are arranged around the cable 1, and the curved pressure surfaces 741 of the compression strip 74 cooperate to limit the position of the cable 1, preventing it from shifting during the braiding process.

[0056] For example, Figure 5 As shown, after the wire swing arm 71 moves the wire end to the braiding position, the wire swing arm 71 continues to swing, causing the curved pressure surface 741 of the compression bar 74 to contact the outer wall of the cable 1. Because multiple wire swing arms 71 are evenly distributed around the cable 1, their curved pressure surfaces 741 work together to form a circular retaining force on the cable 1, ensuring that the cable 1 remains stable during the braiding process. At the same time, the compression bar 74 clamps the wire end, and the wire is guided by the wire swing arm 71 to the outer periphery of the cable 1 for braiding.

[0057] The arcuate pressing surface 741 contacts and limits the outer wall of the cable 1, not only stabilizing the position of the wire ends but also supporting and limiting the cable 1, preventing it from shaking or shifting during the braiding process, thereby improving the braiding quality. This limiting effect ensures that the high-strength fiber wires of the high-temperature resistant special cable 1 are evenly and tightly woven around the outer periphery of the cable 1, improving the insulation and structural strength of the cable 1.

[0058] In some examples, the conductor swing arm 71 is provided with a slide groove 710 arranged along its length, and the slide groove 710 is a long strip-shaped groove. The conductor swing arm 71 is provided with a support frame 9, which includes a threaded rod 901, an extension rod 902, and a curved rod 903. The threaded rod 901 is arranged to pass through the slide groove 710, and its axis direction is perpendicular to the length direction of the slide groove 710. Nuts are provided at both ends of the threaded rod 901 for fixing the threaded rod 901 to the conductor swing arm 71. One end of the extension rod 902 is fixed to the threaded rod 901, and the other end is provided with a curved rod 903. The support frame 9 can slide along the slide groove 710 and can swing around the threaded rod 901. When the support frames 9 on adjacent conductor swing arms 71 swing to a horizontal position, the adjacent curved rods 903 are spliced ​​together to form a support ring 8 for supporting the wire between the spool 5 and the cable 1.

[0059] For example, Figure 4 and Figure 6 As shown, when the conductor swing arm 71 moves to the outer wall of the cable 1, the operator loosens the nuts at both ends of the threaded rod 901, slides the support frame 9 along the slide groove 710 to the appropriate position, and then swings the support frame 9 so that the arc rod 903 is in a horizontal state. The arc rods 903 on adjacent conductor swing arms 71 are spliced ​​together to form a support ring 8. The wire between the spool 5 and the cable 1 is placed on the support ring 8. The support ring 8 supports the wire and prevents the wire and the conductor swing arm 71 from being entangled with each other. After the support is completed, the nuts are tightened to fix the position of the support frame 9. During the braiding process, the wire slides on the outer wall of the support ring 8.

[0060] In some examples, the threaded rod 901 is passed through the slide groove 710, and the position of the threaded rod 901 in the slide groove 710 is adjusted so that the extension rod 902 and the arc rod 903 can swing to a suitable angle. By rotating the nut, the threaded rod 901 is fixed to the wire swing rod 71 to ensure that the support frame 9 is stable. When it is necessary to form a support ring 8, the extension rods 902 and arc rods 903 of each support frame 9 are swung so that adjacent arc rods 903 are spliced ​​together to form a complete support ring 8. After the wire is led out from the spool 5, it passes through the inner wall of the support ring 8 and is smoothly guided to the outer periphery of the cable 1. When the support ring 8 is not needed, the support frame 9 can be swung to a vertical position and stored on the wire swing rod 71 without taking up additional space.

[0061] For example, Figure 4 and Figure 6 As shown, the arrangement of threaded rods 901 and nuts allows for the securement and position adjustment of support frame 9 on wire guide rod 71, providing convenient operation and reliable fixation. The support ring 8 formed by the interconnected curved rods 903 evenly supports the wires, reducing resistance and wear during the guiding process, thereby improving the wire's service life and braiding quality. Furthermore, the detachable and stowable design of support ring 8 does not affect the normal operation of the device when not in use, saving space.

[0062] In some examples, an annular collar 81 is mounted on the outer wall of support ring 8. This collar 81 is a circular ring structure, with its inner wall conforming to the outer wall of support ring 8 and its outer wall being smooth. The inner diameter of collar 81 is slightly larger than the outer diameter of support ring 8, facilitating its placement on support ring 8. Collar 81 can be made of plastic or metal and have a smooth outer profile.

[0063] For example, Figure 6 As shown, after adjacent curved rods 903 are joined to form support ring 8, an annular collar 81 is placed over the outer wall of support ring 8, covering the joint between adjacent curved rods 903. The smooth outer wall of annular collar 81 does not obstruct the wire as it moves along the inner wall of support ring 8. It also obscures the gap at the joint, preventing the wire from getting stuck. To disassemble support ring 8, first remove annular collar 81, then separate the curved rods 903.

[0064] The annular snare 81 effectively shields the joints of adjacent curved rods 903, preventing the wires from entering the gaps and becoming entangled or stuck during movement, ensuring smooth wire guidance. The smooth outer wall reduces friction between the wires and the support ring 8, further protecting the wires. This prevents frictional damage to high-strength fiber wires, particularly, and improves the stability of the braiding process.

[0065] In some examples, the spool 5 is provided with a lead wire device 12, which is a block structure fixed on the top of the spool 5. The lead wire device 12 has a wire channel 1201 inside, which is a curved pipe with a wire inlet 1202 and a wire outlet 1203. The wire inlet 1202 is located on one side of the middle of the outer wall of the spool 5, perpendicular to the axis of the spool 5, and the wire outlet 1203 is located on the top of the spool 5, facing the direction of the wire swing lever 71. The inside of the wire channel 1201 is smooth, used to guide the wire.

[0066] For example, as shown in Figure 7 and Figure 8 , the wire is wound on the spool 5, enters the wire channel 1201 of the lead wire device 12 from the wire inlet 1202 on one side of the middle of the outer wall of the spool 5, passes through the guide inside the channel, and extends out of the wire outlet 1203 on the top of the spool 5. The position of the wire outlet 1203 is opposite to the connecting block 73 of the wire swing lever 71, which facilitates the connection of the wire end with the connecting block 73. During the weaving process, the wire is guided by the lead wire device 12 and is drawn out of the lead wire device 12 on each spool 5 in an orderly manner, avoiding entanglement or knotting of the wires on adjacent spools 5.

[0067] The arrangement of the lead wire device 12 standardizes the wire path, making the wire drawn out of the spool 5 more orderly and reducing the entanglement and knotting of the wire, thereby improving the efficiency of the wire feeding operation. At the same time, the reasonable arrangement of the wire inlet 1202 and the wire outlet 1203 makes it easier for the wire end to connect with the connecting block 73 of the wire swing lever 71, further simplifying the work of the operator and reducing the labor intensity.

[0068] In some examples, the spool 5 includes a fixed shaft seat 51 and a movable shaft seat 52. The fixed shaft seat 51 is provided at the bottom with a buckle matched with the spindle 4, and can be detachably mounted on the spindle 4. The outer wall of the fixed shaft seat 51 is provided with a first clamping tooth 510. The movable shaft seat 52 is provided at the bottom with a clamping groove matched with the fixed shaft seat 51, and the clamping groove is provided with a second clamping tooth 520 matched with the first clamping tooth 510. The lead wire device 12 is arranged on the top surface of the movable shaft seat 52 and is mounted on the fixed shaft seat 51 together with the movable shaft seat 52.

[0069] For example, as shown in Figure 7 and Figure 8 , when installing the spool 5, the fixed shaft seat 51 is first installed on the spindle 4, and then the clamping groove of the movable shaft seat 52 is aligned with the first clamping tooth 510 of the fixed shaft seat 51, and the movable shaft seat 52 is pressed downward so that the second clamping tooth 520 is clamped with the first clamping tooth 510, completing the installation of the movable shaft seat 52. At this time, the lead wire device 12 is located on the top of the movable shaft seat 52 and is used to guide the wire. When replacing the spool 5, the movable shaft seat 52 is lifted upward so that the second clamping tooth 520 is separated from the first clamping tooth 510, and then the movable shaft seat 52 and the lead wire device 12 can be removed, which is convenient and fast.

[0070] The latching connection between the fixed shaft seat 51 and the movable shaft seat 52 enables quick installation and removal of the spool 5. Operators can replace the spool 5 with a simple press and lift motion without the need for tools, significantly improving the efficiency of threading operations. Furthermore, the wire guide 12 is mounted on the movable shaft seat 52 and is replaced along with it, ensuring consistent fit between the wire guide 12 and the spool 5 and avoiding wire guiding issues caused by improper installation of the wire guide 12.

[0071] In some examples, a receiving groove 711 is formed on the wire swing arm 71. The shape of the receiving groove 711 matches the shape of the arc-shaped rod 903. When the support frame 9 swings to the vertical position, the arc-shaped rod 903 can be completely accommodated in the receiving groove 711. The depth and width of the receiving groove 711 are slightly larger than the size of the arc-shaped rod 903, ensuring that the arc-shaped rod 903 can be smoothly inserted and removed.

[0072] For example, Figure 4 As shown, when the support ring 8 is no longer needed, the threaded rod 901 of the support frame 9 is loosened, the extension rod 902 and the curved rod 903 are swung so that the curved rod 903 enters the receiving slot 711 on the wire swing arm 71, and the nuts at both ends of the threaded rod 901 are tightened to secure the support frame 9 in a vertical position. At this point, the curved rod 903 is stored in the receiving slot 711, taking up no extra space and preventing interference with other components. When the support ring 8 is needed, the nuts are loosened, the curved rod 903 is removed from the receiving slot 711, and swung to a horizontal position to join the adjacent curved rod 903. The arrangement of the receiving slot 711 provides storage space for the curved rod 903. When the support ring 8 is not in use, the curved rod 903 can be neatly stored on the wire swing arm 71, keeping the device tidy and preventing collisions and damage caused by the curved rod 903 shaking during operation. This improves the space utilization of the device, making the device more compact and easier to operate.
